Message
Self test failed: xx
Solvent rack leak detected
The cam position is yet
unknown. It is necessary to
run at least 2 revolutions.
The maximum possible flow
for this solvent is (x). Please
reduce the flow rate.
The piston seal leakage has
exceeded the recommended
limit.
The pressure exceeded the
absolute limit.
The primary pressure
exceeded the limit during
calibration.
The pump drive is still in
maintenance position.

Remedial Action
(where xx = additional text)
This message usually appears together with another message
indicating which failure occurred during the self test. Refer to this
message for recommended remedial actions.
The leak sensor in the Solvent Rack has reported a leak.
The Solvent Rack may not be connected properly to the module.
Verify that the Solvent Rack is properly connected to the module.
There is a leak in the system or a fluid connection is loose. Find and
eliminate the source for the leak. Tighten leaking connections and dry
the leak sensor (→ Solvent Rack manual).
The position of the cam is unknown after the piston of the loading
pump has been replaced. Turn on the flow and have the pump run for
two revolutions to establish the position.
(where x specifies the maximum flow rate)
The maximum flow rate for this solvent has been exceeded. Reduce
the flow rate.
Inspect the piston seals for leakage (→ page 186).
Replace the piston seals (→ page 194).
The pressure has exceeded the absolute pressure limit. This message
appears when pressure builds up extremely fast.
NC pump
Each pressure transducer of the NC pump can cause this message.
First, verify that the pressure transducer cables are properly
connected on the flow meter. Disconnect and reconnect the cable.
Then, make sure that the pressure transducers are properly calibrated.
To do so, perform the CalibrateWP command for both pump heads
from Chromeleon.
Reduce the set flow.
If the message is extend by 'Please run the self test', you have to run
the self test before you can continue.
Loading pump
This may happen, for example, when the pump delivers at a high flow
rate while the pump outlet is closed with a fitting plug. Take
appropriate remedial action and retry.
During solvent calibration with the ProFlow flow meter, the primary
pressure exceeded the limit.
The flow meter may be clogged. Purge the flow meter (→ page 75).
An attempt was made to start the pump while the pump is still in
maintenance position, for example, during piston replacement or
piston seal replacement. Return the pistons into the position for
normal operation (→ page 191) and retry.
If the message appears during the internal maintenance procedure for
the loading pump (→ page 142), perform an additional purge cycle
for the loading pump (→ page 76).
